User evaluations of energy efficient buildings - literature review and further research

This chapter gives an overview of research that describes user experiences with different types of energy-efficient buildings, focusing on indoor climate, technical operation, user attitudes and general satisfaction. Energy-efficient buildings are often rated better than conventional buildings on indoor climate, but on digging deeper, users have different concerns. The varying results from the user evaluations reflect that the quality of buildings differs. However, the complaints may also be a result of inappropriate use. The main aim of this chapter is to give guidelines for further research, based on existing user evaluations of energy-efficient buildings. Three important areas for further research on user evaluations could be identified. First, there is a shortage of research that takes into account the social context for evaluation; the social environment, the process of moving into an energy-efficient building and prior knowledge of environmental issues influence evaluation of the buildings. Energy-efficient buildings may also require specific architectural solutions and further research should consider architectural and aesthetic aspects in the evaluation. Research on the use and operation of energy-efficient buildings is increasing, but there is still a need to give more detailed attention to different ways of providing information and training in operation and use.

The interaction between building and users in passive and zero‐energy housing and offices: The role of interfaces, knowledge and user commitment

Purpose – The articles aim is to present user experiences with passive houses and zero‐energy buildings. The focus is on the interaction between the building and the users, specifically on how user interfaces, knowledge, and commitment influence the use of the building and the level of energy consumption awareness.Design/methodology/approach – The study follows an explorative grounded theory approach. This approach generates insights that will be consolidated in follow‐up studies. Qualitative interviews with users of six buildings were conducted. Site inspections applying walk‐through method and other available information complement the data.Findings – Users in general were satisfied with having a new energy efficient building. Several respondents were more concerned about the environment now than before. However, there were concerns about thermal comfort. Misuse or misunderstandings among users in some cases led to lower indoor comfort. New or dissatisfactory design solutions were also responsible for ...
